Product Description
An addressable manual call point, also known as a break glass unit or fire alarm pull station, is a device used to activate a fire alarm signal in the event of a fire or emergency. It is typically installed at easily accessible locations throughout a building, such as exit routes, stairwells, or near fire exits. The manual call point consists of a resettable glass element or push button that, when activated, sends a signal to the fire alarm control panel. The addressable feature allows for individual identification and control of multiple call points, enabling accurate identification of the activated device and precise localization of the emergency.
FAQs:
Q: How does an addressable manual call point work in a fire alarm system?
A: An addressable manual call point is connected to the fire alarm control panel via a network of communication wires. When a person detects a fire or emergency, they can break the glass element or press the activation button on the call point, initiating a fire alarm signal. This signal is transmitted to the control panel, which triggers the alarm notification devices, such as sirens, strobes, and voice evacuation systems. The addressable feature allows the control panel to identify the specific call point that has been activated, providing precise information about the location of the emergency.
Q: What are the advantages of using addressable manual call points in fire alarm systems?
A: Addressable manual call points offer several advantages. Firstly, they provide a reliable and immediate means of initiating a fire alarm signal, allowing individuals to quickly alert others and initiate evacuation procedures. Secondly, the addressable feature enables accurate identification and localization of the activated call point, enabling faster response times for emergency services. Additionally, addressable manual call points provide diagnostic capabilities, allowing the fire alarm system to monitor their status, detect faults, and report any issues for timely maintenance and repair.
Q: Can addressable manual call points be reset after activation?
A: Yes, most addressable manual call points can be reset after activation. Once the emergency situation has been addressed, and it is safe to do so, authorized personnel can reset the call point using a key or tool provided by the manufacturer. It is essential to follow the manufacturer's instructions and consult with fire safety professionals regarding the proper reset procedure to ensure the call point is ready for future activations.
Q: How should addressable manual call points be installed in a building?
A: Addressable manual call points should be installed in accordance with local fire safety regulations and the recommendations of fire safety professionals. They should be placed at easily accessible locations, typically near exit routes, stairwells, or fire exits. The installation should consider factors such as visibility, reachability, and the specific requirements of the fire alarm system. It is crucial to provide clear signage and instructions on the operation of the call points.
